955 dropped a core SCARE

Was looking at installing Linux Mint 10 today and when playing around with the LIVE CD and looking at my hardware I noticed it only recognized 3 cores on the cpu, figuring it was just an error in Linux I rebooted into Windoze to see it was only seeing 3 cores also, at this point I got nervous and pulled up CPU-z and it said 3 cores also.

Now I'm getting really nervous so I took off to the bios and seen that for some reason (probably an I D 10 T error) that one of the cores had been disabled in the bios. Set it to activate the other core and all is well. I really didn't need that this early in the morning

OK figured out what the problem was. It was an I D 10 T error, somehow I set the bios to unlock. With this enabled and cpu leveling set to auto it had disabled the #3 core, I went into the bios and set cpu leveling to manual and enabled the #3 core then set it back to auto and this allowed the core to work. After that I tried a stress test and it kept failing it also would not allow Core Temp to work for some reason so I went back into the bios and found the unlock enabled and once I disabled that everything started working fine. Strange things happen when you hit the wrong keys I guess.

Interesting that the unlock feature disabled core temp reporting even on a quad. It's well known that core temps are disabled with unlocked X2's and X3's ...

I D 10 T errors sounds like my usual kind of problem

If you still have unlocking turned on in the BIOS turn it off. Looks like you already did that.

That is not unusual. I was playing around with ACC this summer with my Athlon II X4 and discovered that I lost temp monitoring when ACC was enabled. I don't think it makes any difference if you start with a locked core or not.

Well this taught me to just go the long route about booting to a CD. Is what happened is I have my bios set to boot from the HD and when I wanted to use the LIVE CD I figured I would just hit the F-key to get to the short cut for booting from CD-Rom well I hit the unlock which is also off of the F-keys as well so this is what started all the problems I just never noticed it did that when I hit the wrong F-key during boot up. Next time I will just go into the bios and set it up to boot from the CD its easier and wont give me a stress test .
